由于区块链没有一个中心化代理来指挥、协调,又要保证每个节点数据的一致性,所以区块链需要一个机制,这个机制需要解决两个基本问题:

Since the blockchain does not have a centralized agent to command and coordinate, the blockchain needs a system to ensure the consistency of data of each node,. This system needs to solve two basic problems:

 

1.这么多人(节点)中谁有权记录数据——一次只有一个人可以记录;

  1. Who has the right to record data in so many people (nodes) – only one person can record at a time;

 

2.其他人(节点)如何同步数据——因为要保持数据的一致性。

  1. How other people (nodes) synchronize data – because data consistency is maintained.
